Anyone know what the purpose of this was for?

I just bought a Bosch T4075 12V 140Ah 800A.

Sorted👍🏻

My 12V 135 AH 850A battery has died. 
just wondered if a smaller one would do the job.

Ha ha. I actually saw someone paint anodes with red oxide once 🙄

I don't think that is correct, assuming a low enough resistance in the cable. The electric cell is between the anode and the closest bit of steel, not the mounting bolt. The bolt and cable are only electrical conductors to complete the circuit. With the slope of the hull side on most boats, I suspect that the anode may well hang clear, so reducing the effectiveness of the cell and fail to protect as larger are as one fixed to the hull. It won't do any harm and might do a bit of good.

Good point. Fortunately my barge has a fair amout of vertical hull just below thw waterline so thats where l ‘ll hang them

[Anodes]

I've just had new anodes welded onto the hull during dry docking. The old ones still have a fair bit left so l thought l might as well hang them down the side of the boat as bin them.

How affective are magnesium anodes when suspended from steel cables (bolted to the hull) into the water?

So to answer your question, never.

How often do members rev their engines to max?

Being on a canal, my 4LW rarely gets the chance.

How often do members check tappets?

[2 bar vs 3 bar water pumps]

Thanks for all the serious educated comments👍

[2 bar vs 3 bar water pumps]

Right. I have a 2 bar pump on my hot water system and  a 2 bar pump on my coldwater system. (so if one packs in l dont lose the whole water supply).
What happens if l replace  one with a 3 bar pump. Thinking of the mixer shower. 
Serious answers only please

Bar is only the cut-out pressure, there should also be litres or gallons per minute in the specifications. That is what you want to look at for a comparison of delivery volume. So the same litres per minute give the same delivery volume. The difference is the 3 bar pump might require a new PRV on the calorifier or its cut out pressure adjusting downwards to 2 bar. Unless adjusted down, it could cause a plumbing leak. Running a tap into the bathroom hand basin is more likely to get you an embarrassing wet patch on your trousers (depending upon bowl design).

So the pressure in the pipework is higher and more suseptable to leakage?

[2 bar vs 3 bar water pumps]

Can someone explain what the difference is if they both deliver the same litres per minute?

No, the accumulator pressure will only affect the length of time between pump blipping on briefly. You have 12 seconds now, and that will go up to maybe a minute or three once you get the pressure set right, depending on the capacity of the accumulator.

 

But the pump will still keep running from time to time as it needs to replace the water leaking out of the system. 

 

My money is on the calorifier PRV letting by and going out of the boat via a skin fitting.

 

 

 

 

No the new pump solved the problem👍

[Leak in water pipe?]

Put another pump on. Sorted. Now post mortem on the old one.

Or water is leaking back through the pump.

Turn off the main valve on the tank outlet. If the pump no longer keeps firing up that would confirm it is water leaking back through the pump. The cause is most likely some dirt in the pump valves.

Thanks.Tried that, but pump still cycling. So hopefully, accumulator just needs repressurisng

Accumulator needs repressurising (or replacing if the bladder has sprung a leak).

Well l've repressurised the accumulator tank up to 2 bar. (It was low). That's the same cut out pressure as on the Whale Watermaster FW1214(B) model. Ran the pump with water tank valve both on and off. Still cycling intermitantly when on and running constantly when off. 

Pump sounds dog rough. 

Time for a new pump???

New pump (always carry a spare) , same problem. Next check PRV🤞

Hi my water pump has started firing up for 1 second every 12 seconds. The pressure vessel is 3 years old. The pump fires up now as soon as l turn the tap on. I cant find any leaks in the pipework. Is there any other possible cause or must there be a leak somewhere?

 

[Leaking stainless steel water tank]

There’s a slight but persistent leak along a bottom welded edge  on my water tank. I’m wondering if one of these recently advertised, leak stopping brush applied “glues” would be worth trying.

We get this sometimes with Mrs M_JG's iphone. Quite often our Amazon Fire stick will not see the mobile hot spot it generates.

 

We normally sort it by shutting the iPhone down and starting it up again. Along with which ever device we are trying to connect.

 

No idea why it does it or why doing this seems to sort it.

Hmm. I'm going to switch eberything off and start from scratch. There is a Firestick too but I've not involved it yet🙄

When you say "doesn't connect" do you mean no RF connection at all, or no Internet?

I'll turn the VPN off. What is RF???

Possible if older it will only cope with 2.5GHz and if the WiFi is 5GHz then it won't have it

The IPad is the latest model.

Yes. But I when I'm at home they use the landline internet. Now I'm aboard the iPad can't connect to my mobile.
